Application filed s 12,

To .aZ Z'w ZzOm it m'ay com em: fBe i known that L'Cnani ns M,-'-BU.LLEIR, a, citizen of theUnited States, and resident of .Milwaukee; in the county of Milwaukee and State of-l/Visc'onsin, have invented new and useful Improvements in Adjustable Heads for Pipes, oflwhich theffollowing is adescription, reference being had to the accompanyin drawings, which are a part of this specification. I

,This invention relates to improvements inadjustable heads for pipescrnore' par tioularlyi adapted forfurnace pipes,

, In heating buildings with hot air furnaces it is'the usual practice to extend round pipes from the furnace in the cellar to the partition walls. and connect said pipes to vertical rectangularpipes which extend up war'dly through. the partitions to ,the res'pejctive rooms to be heated. At the upper ends of the pipes it is usually necessary to mount heads to which registers are c onnected. VVhile the round pipes are of a standard size, the vertical stacks vary crofsslsectional area, due tothe different widths" of studding and thickness of partitionsandin the ordinary construction it necessary to have difierent'sizes of heads'to of various widths.

A further object of the invention is to provide an adjustablehead :t'or pipes which is of simple construction, is strong and durable and is. well adaptedfor the purpose described.

With the above and other objects in view the invention consists of the improved adjustable head for pipes and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views: I I

The head is of rectangular shape and'is" and a side extension out-let register o-pen- 1 .ing The vertical rear wall 1 1, and side walls 15, top wall 16 17 are or: doublewall construction and portions formedwith a lower'inlet or stack o 'enin' 12 ,t p. n

lower portion of the rectangular extension opening 13 of the head. The forward portions 19 and 200i the side walls 15 are bent at right angles, in spaced relation, towards each other to form portions of the front wall of the boot. The front edge portions of the inner parts 19 are bent forwardly.

and then outwardly at right angles as indicated by the numeral 21 and are slightly spaced from the parts 20.

Adjustable U- shaped members22 are positioned between the upper and lower members 16" and 17" and are formed with right angularly extending side extensions 23 which slidably extend betweenthe portions 19 and 20; The

outer edgesjofthe upper and lower-portions of the U-shaped members 22 are bent upwardly and rearwardly to form grooves 24: and 25 into which the front edges of'the por- I tions16' and l7 extend. The inner edge of said upper parts arebent to form grooves I 26 which engage corresponding groovesf27 l formed at the front edges of the inner portion of the double wall 16. The upper edge of the inner portion of the double wall 17 is also bent forwardly and downwardly to form a groove 28 which is engaged by grooved inner edge portions 29 of the lower parts of the U-shaped members 22.

As thus constructed the members'22may be easily moved toward or away from each other to adjust the size of the opening to fit registers of different sizes. 7

It is also to be understood that the head may also be used in connection with floor registers.

From the foregoing description it will be seen that the invention is of very simple construction and is well adapted for the purpose described.

What I claim as my invention is:

1. An adjustable head for pipes, comprising a rectangular casing having double walls with a side opening and an opening at one end, and an angular U-shaped member slidably adjustably connected to and extending between the double walls of the side portion of the casing provided with the side opening for adjusting the width of the side opening.

2. An adjustable head for pipes, compris ing a rectangular casing having double walls with a side opening and an opening at one end of the casing, and angular U- shaped members slidably adjustably connected to and extending between the double walls of the side portion of the casing provided with the side opening and movable towards and away from each other to adjust the width of the side opening.

3. An adjustable head for pipes, comprising a double wall rectangular casing having a side opening and an opening at one end,

outwardly. other portions of the casing adjacent said side opening having grooved edges, and angular U-shaped members positioned between said laterally projecting portions and having grooved edge parts which slidably engage the grooved edges of the casing and being movable towards and away from each otherto adjust the width of the side opening. a

5. An adjustable head for pipes, comp-rising a double wall rectangular casing having an outlet side opening and an] inlet end opening, outer portions of the double wall of said casing above and below said side opening projecting laterally outwardly, inner edge portions of the double wall of said casing adjacent said side opening having grooved edges, andangular U-shaped members positioned between said laterally projecting portions and having grooved edge parts which 'slidably engage the grooved edges of the casing and being movable to: wards and away from each other to adjust the width of the side opening, said U-shaped members also having side extensions which slide between double portions of they double walls.

In testimony whereof I afiix my signature.
